SE removed the "t3-tech-cards" recipe category and replaced it with "science-pack-creation-2". You can fix it yourself by unpacking the mod zip and replacing these two words in the following files: "compatibility-patches\Krastorio2\data.lua" and "compatibility-patches\space-exploration\data-final-fixes.lua"

This worked, Thanks!

Same problem, thanks for the help!
